I Application filed September 12, 1903. Serial No. 172,945. (No model.)

To all whom it may concern.-

Be it known that I, EDWARD T. FRAIM, a

citizen of the United States, residing at Lancaster, in the county of Lancaster and State of Pennsylvania, have invented a new and useful Padlock, of which the following is a specification.

The invention relates to improvements in padlocks.

The object of the present invention is to improve the construction of padlocks and to provide a simple and comparatively inexpensive one of great strength and durability provided with a seamless shell or outer casing and adapted to be assembled and firmly secured together without perforating such shell or outer casing for the reception of rivets or other fastening devices.

A further object of the invention is to provide a padlock of this character which when completed will have the rivets practically concealed and which will present an imperforate rivetless appearance.

Another object of the invention is to provide a padlock adapted to dispense with the ordinary rivets and similar fastening devices for connecting the parts together and to enable the rotary key-guide to be readily mounted on the bottom of the padlock.

Furthermore, the invention has for its object to improve the construction and manner of mounting the spring-actuated bolt for engaging the shackle of the padlock and to permit the bolt to be quickly placed in position in assembling the parts of the padlock.

lYith these and other objects in view the invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended, it being understood that various changes in the form, proportion, size, and minor details of construction within the scope of the claims may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawings, Figure 1 is a perspective view of a padlock constructed in accordance with this invention. Fig. 2 is a plan view of the same. Fig. 3 is a reverseplan View. Fig.

4 is a vertical longitudinal sectional view. Fig. 5 1s a vertical transverse sectional view on the line 5 5 of Fig. 4:. Fig. 6 1s a hori- .zontal sectional view on the line 6 6 of Fig. 4:.

Fig. 7 is a detail perspective view of the inner vertically-divided casing. Figs. 8 and 9 are detail views of the sections thereof. Fig. 10 is a detail perspective View of the sliding bolt. Fig. 11 is a detail perspective view of the bottom cap. Fig. 12 is a detail view of the key.

Like numerals of reference designate corresponding parts in all the figures of the drawings.

1 designates an outer casing consisting of a seamless shell substantially elliptical in horizontal sectional view, as illustrated in Fig. 6 of the drawings, and preferably constructed of steel; but the outer casing may be made of any other suitable material, as will be readily understood, and the shape may be varied, if desired. The outer shell or casing, which is imperforate, as illustrated in Fig. 1 of the drawings, receives an internal body structure or casing 2, which is provided with a top for engaging the upper edges of the outer shell or casing and which is connected with a cap 3, which closes the bottom of the outer shell or casing. The inner casing, which forms a supporting-frame for the locking or shackleengaging mechanism, is composed of vertical laterally-separable members or sections land 5, the inner casing being divided longitudinally, as clearly shown in Figs. 7 to 9, inclusive. The sections which formthe sides of the inner casing are provided at their tops with horizontal flanges or sections 6 and 7 which constitute the top of the padlock-body. The horizontal sections 6 and 7, which are cast integral with the sections of the inner casing, form a cap for engaging the upper edges of the outer shell or casing, and they have straight inner edges 8, which abut when the sections of the inner casing are fitted together, as illustrated in Fig. 7 of the drawings. The outer edges of the horizontal sections of the top or cap are curved or partially rounded at their outer edges at each end to conform to the configuration of the outer shell or casing, and they are provided at their inner edges with end recesses 9 to provide spaces for a shackle 10.

The sections .4; and of the inner casing are provided at their lower ends with integral vertically-disposed rivet-posts 11, which pass through perforations 12 of the bottom cap 3, which is rounded at the ends to conform to the configuration of the outer shell or casing and which is provided at its ends with inwardly or upwardly extending approximately semicircular flanges 13, spaced from the edges of the bottom cap and fitting within the lower end of the outer shell or casing, as clearly shown in Fig. 4: of the accompanying drawings. The inner casing, which extends through the opening of the outer shell or casing, engages the upper edge thereof and is provided with the said top or cap portion for engaging the upper edges of the on ter shell or casing, and when the bottom cap or piece 3 is secured to the lower end of the inner casing by the integral rivet-posts the inner and outer casings are securely connected. By this construction the ordinary rivets and pins are dispensed with, and it is unnecessary to drill or otherwise perforate the seamless outer casing or shell for the passage of the fastening means for securing the inner casing to the same. when the posts 11 are riveted to the bottom cap or piece, the latter presents a smooth outer face, and in the finished lock the outer or lower ends of these posts are practically concealed by the polish or finish, and the lock presents the appearance of a rivetless structure.

In order to enable the inner casing to fit tightly within the outer shell or casing and firmly clamp the same, the sections of the inner casing are provided at their upper ends adjacent to the sections of the t p cap with wedgeshaped lugs 14, presenting outer inclined. edges which extend downward and inward, as clearly shown in Fig. 5, whereby when the inner casing is drawn into the outer casing the parts will be firmly wedged together. These wedge-shaped lugs also serve to brace the sections t and 5 of the inner casing at the outer portions of the sections or pieces of the top cap.

The section 5 of the inner casing is provided with studs '15 and 16, having reduced outer ends, forming shoulders and fitting in perforations 17 and 18 of the section 4. These studs and 16 operate to space the sections 4. and 5, which are also provided with top lugs 19, and the latter lit together and are provided with opposite notches 20, forming a socket when the parts are assembled and adapted to receive the end of a key 21. The key 21 adapted to actuate asliding bolt 22, and he section 5 is provided below the lugs or enlargei'nents with vertical flanges 23, between which are arranged horizontal lugs or flanges 24: and The other section, 4,. is provided with a bottom flange 26, which [its against or is arranged contiguous the adjacent upright flanges 23. The horizontal flanges and 26 are notched, as shown, to provide a passage for the key 21, which is provided with suitable notches to clear the flanges or lugs to enable it to be rotated sui'liciei'ltly to actuate the sliding bolt22. Any number and arrangement of flanges, projections, or lugs may be )rovided, as will be readily understood. These lugs, flanges, and projections are also located at points between the slidable bolt and the keyhole of the lock, and thereby form guards for preventing an instrument from be: ing introduced into the lock for operating the bolt. Should an instrument or tool be introduced into the keyhole, it would be impossible to move the same suliiciently to operate the bolt. The stud 15 forms the pivot 01' the shackle and passes through a perforation at one end of the same, as clearly shown in Fig. at, and the other end of the shackle is provided with a recess, forming a shoulder for engagement with the sliding bolt. One end of the shackle is arranged in one of the end recesses of the top cap and. the other end of the shackle is adapted to project through the other end recess for engaging. the slidable bolt, and when the latter is withdrawn from such engagement the shackle is free to open or swing outward in the usual manner. The slidable belt, which has a beveled head or engaging portion 27, is provided with o1i positely-disposed laterallyextending lugs 28, arranged in opposite hori zontal slots 29 of the sections of the inner casing. The slots, which receive the laterallyextending lugs of the slidable bolt, permit the latter to reciprocate, and the said bolt is posi tively retained in position when the inner and outer casings are assembled, and it is impossible for the bolt to become accidentally displaced. The bolt is actuated by a spring 29, and it has an opening 30, enlarged at one side to form a shoulder and adapted to receive the key,which when rotated engages the shoulder, and thereby reciprocates the bolt against the action of the spring 29. The spring 23), which approximately vi-shaped, is provided with two arms and. has a coil 30 at the bottom to receive the stud 16. The inner arm, which engages the inner or rear end of the bolt, is substantially straight and the other arm, 31, which engages a heel or extension 32 of the shackle, bears against a stud 33, as clearly shown in Fig. 4, in order to secure the necessary stiffness and to prevent the spring from rotating on the stud 33. \Vhen the parts are assembled. the spring is held against lateral movement by a lug or projection 3st extending from .the section t and termii'iatiug short of the section 54.

The bottom cap is provided with a circular opening or aperture 35, in which is arranged a rotary key-guide 36, consisting of a disk, rabbeted at its periphery to provide a reduced portion to fit in the aperture and to form a projecting flange 37 for engaging the inner face of the bottom cap, which is provided with tongues or lugs 38. The tongues or lugs 38, which are formed integral with the bottom cap, are bent inward over the inner or upper face of the rotary keyhole-guide, whereby the latter is retained in position on the bottom cap 3. The upper face of the bottom cap is provided at the aperture with an annular recess to receive the flange of the rotary keyguide, and the inner or upper face of the latter is substantially flush with the inner or upper face of the bottom cap-piece. The keyhole-guide is provided with a slot which is shaped to conform to the configuration of a key, which may be corrugated, as indicated in Fig. 12 of the accompanying drawings. In assembling the parts the tongues or lugs of the bottom cap may bequickly bent inward over the rotary key-guide, and while only two tongues or lugs are illustrated in the accompanying drawings any number may be employed for retaining the key-guide in position. 4

1n assembling the parts of the lock it is only necessary to rivet the posts of the inner casing to the bottom cap and bend down the tongues of the latter, and it will be apparent that a large number of locks may be put togethe'r in a comparatively short time, and that owing to the rivetless structure a lock of great strength and durability is secured. Furthermore, the single riveting of the post of the inner casing operates to fasten the top. the bottom, and inner and outer casings together. Also when the parts are assembled there is no liability of the movable parts becoming, accidentally displaced.
